The most common failure that causes your symptoms is a failure of the SUS boards, or sustain boards which drive the panel. There are two sets of sustain boards, X and Y (or Y and Z for some manufacturers), one set each to drive the horizontal and vertical signals for the panel. The bad news? It isn't something a consumer can diagnose or replace, for the most part. There are DANGEROUS voltages inside your set that can easily kill or cause serious injury. After replacing sustain boards there are certain adjustments required that ned to be performed by a qualified tech. So, you'll need a tecnician to look at it for you. Sorry!

That means that there is an internal error and the tv is in protect mode.

    When this happens it means that there is an internal error and the tv is in protect mode.

    The TV protection circuit detects that there is an internal problem, as a wrong voltage, a short, a capacitor that has blown or a different defectivecomponent.

    After detecting the fault the TV set itself to Protect mode activating a safety switch that will prevent the TV from starting up to avoid further damage.
    The safety switch that keeps turning TV off is also the clicking noise that you often hear when the TV is in this state.

    If the protection circuit was wrong and there is no real problem you can fix this by leaving the TV set unplugged for a couple of hours, so to drain power completely and reset TV eeproms and protection circuit. This for example happens often after a power surge.

    If that does not work, then it means that there is a real fault, in this case you will need to call a technician to test the internal parts.
    If you need to call service you can use the phone number listed on the owner manual.

    Even if problems with Sustain boards are common on Plasma sets, it is not necessarily a sustain board problem.

    Unless you want to take apart the tv by yourself (at your risk) to test Ysus and Zsus, it is still better calling a technician.
    If you want to DIY we can provide guidance.

    I also report here my previous comment for better clarity:

I have had a Hitachi 42" Plasma screen TV for almost 3 years and recently it has had problems. When you turn it on, the TV only stays on for about 10 minutes, and then the screen goes black with the...


The signal from the STU to the Hitachi box is going in the wrong direction.
Is the adaptor that you have switchable? If so, flick the switch in the
other direction and this will fix it. If the adaptor is not switchable get
one that is. Then set the STU output to RGB.

Hope this Helps. -CA

Pioneer 65" TV Model # SD-643HD5 won't power up.


I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?

My Pioneer Plasma Display Model PDP-424mV must be set on a timer as it will turn off approximately 90 seconds after being turned on . I cannot find the "timer" menu selection. How do I fix this?


try looking on your remote, look for a sleep button and proceed to deactivate the sleep timer using the arrow buttons. if this is not the case, then perhaps your internal cpu is allowing the TV to start, then detecting a problem and forcing the tv to turn off again, though i don't see how it would be possible in this case. there are many others better suited to answer that question other than me, but the sleep button is a good start =)
